TabGroupActivity に読み込んでいるアクティビティに少し問題があります
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_profile);
f = new Functions();
String j = f.getUserInfo();
arialFont = Typeface.createFromAsset(this.getAssets(),"Arial.ttf");
username = (TextView)findViewById(R.id.txtProfileName);
firstname = (TextView)findViewById(R.id.txtName);
Address1 = (TextView)findViewById(R.id.txtAdd1);
Cit = (TextView)findViewById(R.id.txtCity);
PostCode = (TextView)findViewById(R.id.txtPost);
Coun = (TextView)findViewById(R.id.txtCountry);
Phon = (TextView)findViewById(R.id.txtPhone);
dob = (TextView)findViewById(R.id.txtDOB);
gender = (TextView)findViewById(R.id.txtGender);
yourDetails = (Button)findViewById(R.id.Button01);
payment = (Button)findViewById(R.id.Button02);
billing = (Button)findViewById(R.id.Button03);
history = (Button)findViewById(R.id.Button04);
yourDetails.setTypeface(arialFont); <-- Null Pointer exception starts here
payment.setTypeface(arialFont);
billing.setTypeface(arialFont);
history.setTypeface(arialFont);
try {
parseData(j);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

ボタンの書体を Arial に設定すると問題が発生することはわかっていますが、なぜこれが問題なのかわかりません。setTypeface 行をコメントアウトすると、正常に動作し、TabGroupActivity 内にボタンの書体が設定されている他のアクティビティに移動し、さらに困惑します。
